can anyone tell me how to check if your ecu is working properly

 

You need to have it put on a fault code reader.

 

do rs turbo ecus have fault codes damn never knew that

i thought if it runs it works

 

you can plug a reader into it if you have the correct software, the car can still run even tho the ecu is fucked, depends which part is fucked, but it will do all sorts of damage

 

I think the only thing that is likely to fail is the integrated MAP sensor. Had that on one of my RSTs once.

 

RST's will run with no fuel ECU....admittedly like a pile of shit but they will do it, they operate like K-Jetronic when something on the fuel management fails.

PeterRST thats the ignition ECU not the fuel one

 

K-jetronic is a bit more complex than KE with no ecu.

Mulla,
Which ecu are you refering to? Nobody said fuel ecu but Safechav.

 

its the one behind the heater blower,when i start her up she starts for one second then stops,keeps doing that when it starts up black smoke comes out if i turn her off and try again it wont start keeps doing that,before this happend it sounded like it was fireing on three cylinders,it gradually got worse i changed the plugs as they were black,changed leads but still same problem just does not fire up,so i think its the ecu or metering unit any help please.

 

Ahhhh sorry im sure i read fuel ECU

And jesse you are right i know K is a bit more complicated then KE without an ECU, hence why KE wont start well from cold when the management fails

 

were is the fuel ecu

 

Next to the silver ignition ECU, its black.

 

just stripped the metering unit down just in case looked alright .i put it back on the car but did not put the injection pipes back on fuel came out of the coldstart hole so fastened that back on but on the injectors fuel only came out of one what do you think.

 

Sounds like its got an internal fault

 

going to have to replace it to try it out anyone got one

 

Its got to be fauly if one sprays fuel the other 3 should spray equally, its continuous injection

 

i hope so got one on its way now
